LAPPET AND THREAD GUIDE OF SPINNING, TWISTING, AND LIKE MACHINES.

Application filed September 27, 1924, Serial No. 740,326, and in GreatBritain September 28, 1921.

This invention relates to lappets and cylinder of small diameterextending across I the forward portion of the lappet and below the uppersurface thereof; the said tube is provided with holes bored transverselythereof to receive the shank of the thread guide and the inner walls ofthe said tube are tapped, on one or both sides of the trans verse holes,to accommodate a grub screw or other set screw adapted to bear againstthe portion of the shank that crosses" the tube, thus clamping thethread guide in position.

In the accompanying drawings Figure l is a side elevation,

Figure 2 is a front elevation, with the shank of the thread guide shownin section, and

Figure 3 is an inverted plan of one construction of lappet and threadguide according to this invention.

i'fiigures at and 5 are views of details.

A is a lappet, which is secured at its rear end to a lappet board B by ascrew passing through a hinge member 0, and which car ries at itsforward end a thread guide D termed of wire bent as shown. The lappet $1is made of sheet metal and comprises a top plate a and side flanges a awhich form bracket supports for the lappet when in its horizontalposition as shown in Figure 1.

a is a tube extending across the front of the lappet and formed bybending the forward portion of the top plate into the position shown.The said tube a has two holes bored transversely throughit, and on thecentre line of the lappet, to receive the shank D of the thread guide D;and one or both ends of the tube a are tapped to receive a grub screw E(Figure 4) the forward end of V which is screwed tightly against theportion of the shank D" that lies within the tube a and thus clamps thethread guide in the required position.

Having described my invention what I of which is bentto form acylindrical bushing the interior of which is tapped and in the walls ofwhich are cut oppositely situated holes on a line transversely of thebushing, the said holes being adapted to receive the shank of the threadguide, and a set screw adapted when screwed into the bushing to abutagainst the portion of the thread guide shank that crosses the saidbushing.

2. In a lappet and thread guide i oi spinning, twisting and likemachines, the combination with a thread guide of a lappet comprising ametal plate provided at its forward end with, an axially interiorlythreaded bushing, said bushing being transversely apei'tured to admitthe shank of a thread guide, a thread guide in the apertui'ed part ofsaid bushing intersecting the bore of said bushing and a setscrewscrew-v ing directly axially into said bushing, and coacting directlywith that portion of the shank of the thread guide which lies in itsAugust, A.
